Abstract
The present work refers to a development of texture and microstructure in wires of AISI 302 austenitic steel subjected to multistage drawing process. The analysis of texture focused on pole figures, orientation distribution functions (ODFs) and inverse pole figures. The texture measurements were conducted on the sections parallel to the wire axis. The microstructure was observed using optical and transmission electron microscopes. The rnartensitic transformation (gamma –> alpha') was induced by plastic deformation in the whole range of deformations. The texture development of both phases i.e. austenite and martensite was analysed. The texture components were characterized by crystallographic direction parallel to the axes of the wires. The 111 and 001 orientations were main components of the austenite texture, while, in the martensite they were 110 and 021 ones. The equiaxial grains of austenite containing annealing twins were observed within the microstructure in the initial state. During the deformation process the shape of austenite grains changed into long slim bands parallel to the drawing direction. Many shear bands were observed in the microstructure at large deformations. The martensite, which formed as a result of deformation induced transformation (gamma –> alpha'), influenced properties of the steel. The hardening of the material resulted from a significant increase of the volume fraction of the alpha'-martensite in the structure of the steel.
